为了获取黑龙江省松嫩平原北部农田精确质量评价结果,采用ARCGIS平台、DELPH(特尔斐)模型与AHP结合专家经验对选取的1988个土壤样本进行了质量评分,并根据累计曲线法划分地力等级。结果表明:研究区1级耕地占总面积的5.13%;2级耕地占22.45%;3级耕地占44.98%;4级耕地占22.62%;5级耕地占4.82%。为准确地反映了该研究区域耕地土壤质量的差异。
In order to obtain the accurate assessment of farmland quality in the northern Songnen Plain of Heilongjiang Province, 1988 soil samples were evaluated by using ARCGIS platform, DELPH (Delphi) model and AHP combined with experience of experts. Soil geography was divided according to the cumulative curve method . The results showed that the first grade arable land in the study area accounted for 5.13% of the total area, the second grade cultivated land accounted for 22.45%, the third grade cultivated land accounted for 44.98%, the fourth grade cultivated land accounted for 22.62% and the fifth grade cultivated land accounted for 4.82%. In order to accurately reflect the difference of cultivated land quality in the study area.
